The NVIDIA SHIELD TV Pro is indeed coming as leaked by Amazon yesterday. Rumors began pointing in that direction about three months ago and as it turns out, they were true.

9to5Google spotted the listing and was able to catch all of the information before the page was taken down. The NVIDIA SHIELD TV Pro will feature a Tegra X1+ processor that's said to be up to 25% faster than the previous Tegra X1, support for Dolby Vision and Dolby Atmos (in addition to HDR), a built-in Chromecast Ultra (which will likely be used for Google Stadia, too, just like the rumors said), and support for both Google Assistant and Amazon Alexa. Additionally, HD video will be upscaled to 4K through AI.
